What song makes you want to write a letter?

I can't remember the last time I wrote a letter. Possibly in my early 20s when my Gran and I used to exchange letters now and then. I'd moved to the south of England, and her hearing wasn't always the best on the phone so it was easier to jot down a few updates on paper. I still have her replies somewhere.

Given letter writing wasn't a big part of my upbringing, nor my adult life, I guess what I'm looking for in a song that MAY inspire such a notion is, just that, inspiration. What song makes me so full of emotion that I want to capture that in a letter to someone?

I stumbled across The Paper Kites through an old friend, and this song has been in my playlists since then. The idea of someone filling your head so completely that all you want to do is be close to them is something I'm familiar with but landed hardest when Becca and I first got together. Some times we'd lie in bed and chat for hours, just to be next to each other, and it still didn't feel enough, I always wanted more of her time, of her essence and soul, of her being.

I still do.
